Which of the following statements describes the Medellin Cartel? A. I was a Venezuelan cartel that determined oil prices between 1971 and 1993.
B. It was a Bolivian cartel that continues to control the diamond exports from that country.
C. It was a Colombian cartel that controlled the cocaine trade with North America in the 1970s and
1980s.
D. It was a Mexican cartel that smuggled marijuana across the United States border in the 1970s

The correct answer is C. It was a Colombian cartel that controlled the cocaine trade with North America in the 1970s and  1980s.

Explanation:

C is correct answer because the cartel itself was created in Colombian city of Medellin. It didn't only controlled only the drug trade, but it was also regarded as a terrorist organization. It was led by Pablo Escobar.

Other options are not correct because they are not connected with the Medellin cartel, that as we have said operated from Colombia.
